The demand on naval and commercial fleet assets has never been greater than it is today. Owners and operators are looking to reduce their current year capital expenditures as much as possible, which in turn is pushing the currently operating vessels into longer than planned service lives. This industry trend is driving a greater number of complex repairs, overhauls and large service life extension programs. In order to support this effort, the industry has started to turn to 3-D Computer Aided Design (CAD) as a repair and overhaul tool.
